Research Interests

My research interests include design automation for intelligent cyber-physical systems (CPS) and Internet-of-Things (IoT) applications, safe and robust machine learning for embodied AI systems, cyber-physical security, energy-efficient CPS, and system-on-chip design.

Recent work in my group has been focusing on system-level synthesis, optimization, verification, and modeling methodologies for intelligent cyber-physical systems. We are particularly interested in addressing safety, robustness, security, adaptability, resiliency, and energy challenges in the design and operation of embodied AI systems. We work on applications in the domains of connected and autonomous vehicles, robotics, advanced manufacturing, wearable computing, smart buildings and infrastructures, and IoT.
